Docker hit the developer scene in a big way last year. It made it easy for developers to run their applications locally and easily share and deploy them. But it wasn't quite ready for prime-time. It wasn't easy to run n-tier applications locally, manage Docker across different geographical locations or cluster Docker for availability and performance. Recent releases of Docker have introduced new capabilities and tools to help with these use cases. In this session we're going to look at these new capabilities including: * Looking at Docker Compose for building n-tier Docker applications and managing application stacks. * Introduce Docker Swarm which provides orchestration and clustering for Docker servers. * See how to integrate Docker and service discovery tools. By the end of the session, you'll have a good understanding of how to take your Docker implementation to the next level and make use of these new capabilities.

15. Docker Compose
Because it's not simple to build a
stack
15

16. Docker Compose
• Fast, isolated development environments using Docker.
• Quick and easy to start.
• Manages a collection of containers.
16

17. Installing Compose
$ sudo pip install -U docker-compose
$ docker-compose --version
17

18. Compose basics
• Build your apps with Dockerfile's.
• Combine applications and images with a docker-
compose.yml file.

19. The Dockerfile
FROM ubuntu:14.04
RUN apt-get -yqq update
RUN apt-get -yqq install nodejs npm
RUN ln -s /usr/bin/nodejs /usr/bin/node
RUN mkdir -p /var/log/nodeapp
ADD nodeapp /opt/nodeapp/
WORKDIR /opt/nodeapp
RUN npm install
19

20. The docker-compose.yml file
db:
image: redis
ports:
- "6379"
web:
image: jamtur01/0redevdemo
command: nodejs server.js
ports:
- "3000:3000"
links:
- db
20

21. Compose details
• Can build images, use existing or pull images
• Can map ports, manage links and create volumes
• Still single host centric.

22. Start Compose
$ sudo docker-compose up

Creating compose_web_1...

24. Compose benefits
• Build complex local stacks.
• Consistent and shareable.
• No more...

27. Machine benefits
• Automatically build Docker servers.
• Manage Docker servers.
• Target local and cloud nodes.

29. Docker Swarm
• Clustering (management) for Docker.
• Manage multiple Docker daemons.
• Distribute workloads.

32. Kubernetes
• Based on Google's container model
• Turns containers into nodes

33. Mesosphere
• Workload management & scheduling
• Docker is an option
